ROPE

Application filed July 15,

Fig. 1 is a side view of a rope clamp constructed in accordance with myinvention; and i Fig. 2 is an edge view ofthe same.

This invention relates to improvement n rope-grips particularly adaptedfor use 111 connection with scaft'oldings or tackles gen erally, whereit is desirable to have means to hold the rope against movement 1n onedirection, but free to move in the opposite direction, the object beingto provide means by which the rope will be firmly gripped and readilyreleased, and the invention consists in the construction as hereinafterdescribed and particularly recited in the clalm.

In carrying out my invention, I employ a cross-piece 5 formed atopposite ends Wl'tll eyes 6 and 7, through which a rope may pass.Extending upward from the crosspiece is a longitudinally-slotted post 8formed near its upper end with a stop9, and at its upper end with an eye10. Mounted in the post, betweenthesides thereof, upon pin 11, is athree-armed rope-gu1de 12, and also pivotally mounted in the post, 111stbelow the stop 9 upon a pivot 13, 1s a latch let formed at its lower endwith a block arranged to enter between two or the arms of the rope'guide12, but free to swing clear of it.

The ends of the arms of the guide are grooved to receive the rope, andthis guide turns as the rope is moved and the rope is gripped by directpressure between one of the arms and the latch and the use of roll ersin the guide is avoided.

At the upper end the latch 14; is formed with a stop-shoulder 16 toengage with the stop 9 and with an outwardly-projecting releasing-arm17, to which a cord 18 is attached. The latch is drawn to its lockingposition by a spring 19, one end of which is fixed to the latch and theother end to a pin 20 extending between two lugs 21 and 22 extendingoutward from the sides of thepost The cross-piece 5 may also be providedon its underside with a downwardly-extending eye 23, to which one end ofa rope may be attached. A rope 24: extends upward through the eye 7 overthe arms of the rope-guide 12 and downward through the eye 6, and in thenormal position, the block 15 of the latch will stand between two of theGRIP.

arms, and tension upon the end 25 of the rope will cause one of the arms26 to clamp the rope between that arm and the block 15.

The end 27 of the rope, however, can be pulled down, and in so pullingthe block 15 is moved forward, as shown in broken lines in Fig. 1, andthe rope is free to travel, and in traveling turns the rope-clamp. Assoon as downward pull upon the end 27 is released, one of the arms willagain clamp the rope between that, arm and the block. Should itbedesired to move the rope in the opposite direction, that is, to letthe end 25 down, a pull upon the cord 18 will move the latch 14 out or.engagement with the rope, so that the rope will then be free to travelin either direction.

One advantage of using a three-armed rope-guide is that sufiicient spaceis provided between the arms to permit the use of a single device withvarying sizes of rope, and the advantage of providing a crosspiece witheyes through which the rope passes is to always maintain the rope inline with the three-armed ropeguide. If these eyes are not present, therope is quite liable to swing out of line with the arms and consequentlybecome ammed.

I thus provide, in a very simple way, a rope-clamp which is positivelyeffective in gripping a rope to prevent its moving in one direction, butleaving it perfectly free to be moved in the opposite direction.

I claim:

A rope-clamp, comprising a cross-arm formed at opposite ends with eyes,through which the rope passes, a slotted post extending. upward fromsaid cross-arm and provided at its upper end with an eye and with astop, a three-armed rope-guide rotatably mounted in said post, theendsof the arms formed with notches, a latch mounted in said post above saidguide and provided at its lower end with a block extending into the pathof the arms of the guide, said latch formed at its upper end with a stopand with a releasing-arm extending outward therefrom, and a springtending to draw the latch into the path of movement of one of the armsof the said guide.

In testimony whereof, I have signed this specification.

ANDREW LUOIBELLO.
